The Walking Dead cast may have too many people, but generally they do give arcs that turn those folks around. Did you expect Norman Reedus' character to become a fan favorite when he was first introduced in season 1 (granted this was before LOL OMG NORMAN REEDUS! *FANGIRL* happened to get Darabont to keep him and his "brother" on the show)? Carol going from abused house-wife to the Terminator/Assassin's Creed house-wife-killer?
To be fair, it took them 3-4 years to figure out what to do with Carol and Daryl only became a thing like maybe in late season 2. We have no idea what kind of arcs the characters of FtWD are on.
